The present paper examines a recent attempt to deduce the EPP from labeling. Chomsky (2015) argues that the EPP is reducible to Label Weakness. In this paper, I first point out that Label Weakness raises problems that are not faced under the EPP. I then propose that pair-Merge (i.e. the Merge that yields an asymmetric structure) provides a solution to Label Weakness, claiming that Merge, together with Label Weakness, explains the EPP. I show that the proposal brings theoretically and empirically favorable consequences. Given the proposed analysis, I also argue that externalization is the other side of the EPP, demonstrating that it explains the EPP when a labeling problem is solved and that it reduces parametric variations with the EPP to the peripheries of the computation. This paper argues that Merge plays a key role in language and endorses the Merge-based language design proposed in the Minimalist Program.

关于从标签中扣除 EPP*

本文研究了最近从标签中推断 EPP 的尝试。Chomsky (2015) 认为 EPP 可以简化为标签弱点。在本文中，我首先指出标签弱点引发了 EPP 未面临的问题。然后我提出pair-Merge（即产生不对称结构的Merge）为Label Weakness 提供了一种解决方案，声称Merge 与Label Weakness 一起解释了EPP。我表明该提议带来了理论上和经验上的有利结果。鉴于所提出的分析，我还认为外部化是 EPP 的另一面，证明它在解决标记问题时解释了 EPP，并且它减少了计算外围的 EPP 的参数变化。
